In March 2021, the Internet Engineering Task Force (IETF) released RFC 8996, classified as a current best practice, officially announcing the deprecation of the TLS 1.0 and TLS 1.1 protocols. If your applications and web services are still using these protocols, please stop immediately and update to TLS 1.2 or TLS 1.3 protocol versions as soon as possible to eliminate any possible security risks.
By chance, I came across a picoCTF RSA challenge called Sum-O-Primes. This problem is not difficult, you can do it by knowing the basics of the RSA algorithm. In addition, if you are familiar with the history of the evolution of the RSA algorithm, you can find a second ingenious fast solution.
Memory access errors are the most common software errors that often cause program crashes. The AddressSanitizer tool, developed by Google engineers in 2012, has become the first choice of C/C++ programmers for its wide coverage, high efficiency, and low overhead. Here is a brief introduction to its principle and usage.
IPv6 supports multiple addresses, making address assignments more flexible and convenient. Unlike IPv4, which relied solely on the DHCP protocol for address assignment, IPv6 incorporates a native Stateless Address AutoConfiguration SLAAC) protocol. SLAAC can either work alone to provide IPv6 addresses to hosts, or it can work with DHCPv6 to generate new assignment schemes. Here is a comprehensive analysis of the dynamic address allocation mechanism for IPv6.
The problem of Endianness is essentially a question about how computers store large numbers.
